Sic ion implantation mask
WebFeb 1, 2024 · Therefore, SiC power devices are also known as “green energy” devices that drive the “new energy revolution.” Among the main milestones for SiC device fabrication, … WebLocal doping of semiconductors is usually performed by diffusion or ion implantation through a mask. In the case of SiC, standard diffusion techniques cannot be use d because of the small diffusivity of dopants in this material. On the other hand, ion implant ation is generally used even if some problems are still unsolved, specially for Al doping.
